IMPROVEMENT IN MACHINES FOR CUTTING SHANK-STIFFEN'ERS EOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 1 70,135, dated November 16, 1875 application filed October 28, 1875.

To all whom it may concern:

Be it known that I, JEREMIAH M. WATSON, of Sharon, of the county of Norfolk and State of Massachusetts, have invented a new and useful machine for cutting from a sheet of leather or other suitable material shankstift'eners for the soles of boots or shoes; and do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 denotes a top view, Fig. 2 a side elevation, Fig. 3a fro'nt-end view, Fig. 4 a

transverse section, and Fig. 5 a longitudinal section, of such machine.

' In this machine there is employed with a bed for the support of the material to be out two reciprocating knives, which are inclined to the bed, each of them, while in movement, being made to cross the path of the other, whereby they are caused to cut from the sheet a shank-stiifener, beveled in opposite directious on its opposite edges.

In the drawings, A and B represent the said knives, which are fixed to carriers 0 D,

inclined to each other and the bed E in manner as shown. These carriers are supported in inclined grooves a a a a, made in the two opposite side portions b b of the frame F, for supporting the bed E. To each of the carriers two connectingrods, G G, are hinged, they, at

their lower parts, being secured to collars or rings H H, that encompass eccentrics I I, fixed on a'horizontal shaft, K, all being arranged as represented. 0n revolving the shaft each knife will not only be moved to ward and away from the bed, but in doing so will cross the path of theother knife, whereby the sheet of material supported on. the bed and cut through, first by one knife and next by the other, will be in the form of a shankpathway of the other, so that the material,

after being cut by them, is beveled at opposite edges, as and for the purpose described.
